Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of household appliances, specifically, relates to a temperature probe and cooking utensil. BACKGROUND

[0002] When the volume of the food material in the cooking cavity is large, the temperature at the center of the cooking cavity is greatly affected by the food material, and the temperature value detected by the temperature measuring device arranged on the cooking utensil box body is greatly different from the temperature value around the food material. At this time, detection needs to be carried out through the temperature probe. However, the temperature probe in the related art only arranges a temperature sensor at the tip, and the temperature sensor is inserted into the food material, which leads to the fact that the temperature probe can only detect the temperature inside the food material. SUMMARY

[0003] The utility model aims at least to solve one of the technical problems existing in the prior art or related art.

[0004] Therefore, a first object of the utility model is to provide a temperature probe.

[0005] A second object of the utility model is to provide a cooking utensil.

[0006] In order to achieve the above at least one object, according to the first aspect of the utility model, a temperature probe is provided, the temperature probe is used for a cooking utensil, the cooking utensil includes a cooking cavity for containing food material, and the temperature probe includes: a first probe part for detecting the temperature of the food material, the first probe part includes: a probe main body, at least a part of the probe main body is used for inserting into the food material, the probe main body has a first end and a second end which are away from each other, and the first end can be inserted into the food material; At least one first temperature sensor is arranged on the probe main body, and the first temperature sensor is close to the first end, and the first temperature sensor is used for detecting the temperature of the food material; At least one second temperature sensor is arranged on the probe main body, and the second temperature sensor is used for detecting the temperature of the cooking cavity; wherein the second temperature sensor is arranged on the probe main body, the probe main body has a limiting line, the limiting line is used for indicating the depth of the probe main body inserted into the food material, the first temperature sensor is located on one side of the limiting line towards the first end, and the second temperature sensor is located on one side of the limiting line towards the second end; and / or the temperature probe further includes: a second probe part close to the second end, in the case that the first probe part is inserted into the food material, the second probe part can have a spacing between the food material, and the second temperature sensor is arranged on the second probe part.

[0007] The temperature probe provided in the present application can be applied to a cooking utensil. The cooking utensil used by the temperature probe has a cooking cavity for containing food material, and the temperature probe can be inserted into the food material and detect the temperature of the food material and the ambient temperature around the food material.

[0008] The temperature probe comprises a first probe part, at least a part of the first probe part being capable of being inserted into the food material and detecting the temperature inside the food material. The first probe part comprises a probe body and a first temperature sensor, at least a part of the probe body being capable of being inserted into the food material when the temperature of the food material is detected by the temperature probe, and the first temperature sensor is arranged on the probe body, and when the probe body is inserted into the food material, the first temperature sensor extends into the food material together with the probe body, so that the temperature inside the food material can be detected by the first temperature sensor. Specifically, the probe body has a first end and a second end, the first end and the second end are away from each other, the first end is capable of being inserted into the food material, and the first temperature sensor is close to the first end. In this way, the first temperature sensor can be inserted into a position closer to the center of the food material, so as to improve the accuracy of the temperature detection of the food material by the first temperature sensor.

[0009] Further, the width of the probe body gradually decreases in the direction towards the first end of the probe body, and the first end of the probe body is in a pointed structure, so that the probe body can be more easily inserted into the food material. The number of the first temperature sensors can be one or more. When the number of the first temperature sensors is more than one, the plurality of first temperature sensors can be arranged in sequence along the length direction of the probe body, or can be arranged at the same position along the length direction of the probe body. The first temperature sensor can be arranged inside the probe body, i.e. the first temperature sensor is not exposed outside the probe body, so that the first temperature sensor can be protected by the probe body. The probe body can be heat-conducting, and the heat of the food material can be transmitted to the first temperature sensor through the probe body. The first temperature sensor can also be arranged on the surface of the probe body, so as to improve the detection accuracy of the first temperature sensor. The probe body can be made of stainless steel.

[0010] Further, in order to detect the ambient temperature around the food material, the present application further provides a second temperature sensor in the temperature probe, and when at least a part of the probe body is inserted into the food material, the second temperature sensor is located outside the food material, so that the ambient temperature around the food material in the cooking cavity can be detected by the second temperature sensor.

[0011] In one possible implementation, the temperature probe further comprises a second probe portion, the second probe portion being located close to the second end of the probe body, that is, when the probe body is inserted into the food material, the second probe portion is located on the side of the probe body away from the food material. In this way, the second probe portion can be spaced apart from the food material when the first probe portion is inserted into the food material. The second temperature sensor is arranged in the second probe portion. Specifically, the second temperature sensor is arranged in the interior of the second probe portion, and when at least a portion of the probe body is inserted into the food material, the second probe portion is spaced apart from the food material, so that the second temperature sensor is located outside the food material. The second probe portion is made of a material with good thermal conductivity, so that the second probe portion can conduct heat, and the second probe portion transmits heat of the environment around the food material to the second temperature sensor, so that the second temperature sensor can detect the ambient temperature of the food material. Moreover, compared with the temperature detection component arranged on the wall of the cooking cavity, the second temperature sensor is closer to the center of the cooking cavity, and thus the temperature detection result of the second temperature sensor is more accurate.

[0012] In another possible implementation, the second temperature sensor is arranged in the probe body. The probe body has a limiting line, the limiting line being located close to the second end of the probe body, and the limiting line is used to indicate the depth of the probe body inserted into the food material. Specifically, when the user inserts the probe body into the food material, the insertion depth of the probe body can be observed through the limiting line, and the limiting line is kept outside the food material, or the probe body is inserted to the position of the limiting line. The first temperature sensor and the second temperature sensor are respectively located on the two sides of the limiting line, the first temperature sensor is located on the side of the limiting line toward the first end, and the second temperature sensor is located on the side of the limiting line toward the second end. When the probe body is inserted into the food material, the second temperature sensor is located on the side of the limiting line toward the second end, so that the second temperature sensor is located outside the food material. Compared with the structure in which the second temperature sensor is arranged in the second probe portion, arranging the second temperature sensor on the probe body can make the second temperature sensor closer to the food material, and thus the temperature value detected by the second temperature sensor is closer to the temperature at the center of the cooking cavity, and the temperature detection result of the second temperature sensor is more accurate.

[0013] By arranging the first temperature sensor and the second temperature sensor in the temperature probe, and arranging the second temperature sensor outside the food material, the temperature inside the food material can be detected by the first temperature sensor, and the ambient temperature around the food material can be detected by the second temperature sensor. Compared with the temperature detection component arranged on the wall of the cooking cavity, the second temperature sensor is closer to the center of the cooking cavity, so that the temperature value close to the center of the cooking cavity can be obtained, and the accuracy of temperature detection of the temperature probe is improved. The cooking utensil can accurately obtain the temperature at the center of the cooking cavity even when the volume of the food material is large, so that the cooking utensil can more accurately control the temperature, improve the temperature recovery speed in the cooking cavity, and improve the cooking effect of the cooking utensil.

[0014] According to the temperature probe of the utility model above, the following distinguished technical features can also be provided:

[0015] In some technical solutions, the temperature probe further comprises: a first handle, the second end of the first probe part is connected to one end of the first handle, and in the case that the temperature probe comprises a second probe part, the second probe part is connected to the other end of the first handle, and the first handle can be insulated and can be heat-insulated.

[0016] In this technical solution, the structure of the temperature probe is further limited. The temperature probe further comprises a first handle, which on the one hand facilitates the user to hold the temperature probe, and on the other hand can block the first probe part and the second probe part through the first handle. Based on the different positions of the second temperature sensor, the first handle has two different positions. In the case that the second temperature sensor is arranged on the second probe part, the temperature probe comprises a second probe part, and the second ends of the first probe part and the second probe part are respectively connected to the two ends of the first handle. In the case that the second temperature sensor is arranged on the probe main body, the first handle is connected to the second end of the first probe part.

[0017] Specifically, the first handle is made of insulating and heat-insulating material, such as silicone rubber material. In this way, the first handle can be prevented from electric leakage, and the temperature of the first handle can be prevented from being too high, facilitating the user to hold it. Further, since the first handle is made of insulating and heat-insulating material, the first handle can block the heat conduction between the probe main body and the second probe part, so as to avoid affecting the temperature detection of the first temperature sensor and the second temperature sensor, and improve the temperature detection accuracy of the temperature probe.

[0018] In some technical solutions, the first probe part further comprises: a heat-conducting member arranged in the probe main body and in contact with the first temperature sensor, and the heat-conducting member can conduct heat.

[0019] In the technical solution, the structure of the first probe part is further limited. In order to improve the heat conduction effect of the probe body, the heat conduction piece is further arranged in the first probe part. Specifically, the heat conduction piece is made of a heat conduction material with excellent heat conduction, so that the heat conduction piece can conduct heat, and the heat conduction piece is arranged in the probe body and in contact with the first temperature sensor. Understandably, when the first temperature sensor is arranged in the probe body, the probe body transmits the heat of the food to the first temperature sensor, so that the first temperature sensor can detect the temperature in the food. If the heat conduction effect of the probe body is poor, the detection accuracy of the first temperature sensor will be reduced. In order to avoid this problem, the heat conduction piece is arranged in the probe body, which can be made of a material such as resin with excellent heat conduction effect. The heat conduction piece is in contact with the probe body and the first temperature sensor, so that the probe body transmits heat to the first temperature sensor through the heat conduction piece. Since the heat conduction piece has excellent heat conduction, it can improve the heat transfer speed and reduce heat loss, thereby improving the temperature measurement speed and accuracy of the first temperature sensor. The heat conduction piece can be filled in the probe body.

[0020] By arranging the heat conduction piece in contact with the first temperature sensor in the probe body, heat can be transmitted to the first temperature sensor through the heat conduction piece, thereby improving the temperature measurement speed and accuracy of the first temperature sensor.

[0021] In some technical solutions, the probe body and the second probe part are metal components.

[0022] In the technical solution, the probe body and the second probe part are further limited. Specifically, the probe body and the second probe part are made of metal material. When the first temperature sensor is arranged inside the probe body, heat needs to be transmitted to the first temperature sensor through the probe body. When the second temperature sensor is arranged in the second probe part, the second temperature sensor can be located inside the second probe part, and at this time heat needs to be transmitted to the second temperature sensor through the second probe part. By arranging the probe body and the second probe part to be made of metal material, the probe body and the second probe part can have excellent heat conduction, thereby improving the temperature measurement accuracy of the first temperature sensor and the second temperature sensor.

[0023] In some embodiments, the cooking utensil further comprises a temperature control device configured to adjust the temperature in the cooking cavity, and the temperature probe further comprises: a first signal line connected to the first temperature sensor, the first temperature sensor being configured to generate a first temperature signal when detecting the temperature of the food material, and the first signal line being configured to transmit the first temperature signal; and a second signal line connected to the second temperature sensor, the second temperature sensor being configured to generate a second temperature signal when detecting the temperature of the cooking cavity, and the second signal line being configured to transmit the second temperature signal; wherein the first signal line and the second signal line are electrically connected to the temperature control device.

[0024] In this embodiment, the structure of the temperature probe is further limited. The cooking utensil comprises a temperature control device configured to adjust the temperature in the cooking cavity. When the cooking utensil heats the food material, the temperature probe detects the temperature of the food material and the ambient temperature around the food material. After the first temperature sensor and the second temperature sensor detect the temperature of the food material and the ambient temperature around the food material, respectively, the temperature values detected by the first temperature sensor and the second temperature sensor need to be converted into signals and transmitted to the temperature control device. In order to transmit the signals generated by the first temperature sensor and the second temperature sensor to the temperature control device, the first signal line and the second signal line are further provided in the temperature probe.

[0025] Specifically, the first signal line is connected to the first temperature sensor, the first temperature sensor is configured to generate a first temperature signal when detecting the temperature of the food material, and the first signal line is configured to transmit the first temperature signal.

Further, the first signal line and the second signal line are electrically connected to the temperature control device. In this way, the first temperature signal and the second temperature signal can be transmitted to the temperature control device through the first signal line and the second signal line, respectively, so that the temperature control device can adjust the temperature in the cooking cavity according to the detection results of the first temperature sensor and the second temperature sensor.

[0026] In some embodiments, the temperature probe further comprises a plug electrically connected to the first signal line and the second signal line.

[0027] In this embodiment, the structure of the temperature probe is further limited. The cooking utensil comprises a box body having a probe socket, and the temperature probe is detachably connected to the probe socket. When the user needs to detect the temperature in the cooking cavity through the temperature probe, the user can connect the temperature probe to the probe socket, and when the user does not need to use the temperature probe, the user can separate the temperature probe from the probe socket. The temperature probe comprises a plug that can be detachably connected to the probe socket to realize the connection and separation of the temperature probe and the probe socket.

[0028] Specifically, the first signal line and the second signal line are respectively electrically connected with the plug, the plug is capable of being connected with the probe socket, when the plug is connected with the probe socket, since the probe socket is electrically connected with the temperature control device, the electrical connection between the plug and the temperature control device can be realized. In this way, the temperature probe can transmit the first temperature signal and the second temperature signal to the temperature control device, so that the temperature control device can adjust the temperature in the cooking cavity according to the detection results of the first temperature sensor and the second temperature sensor.

[0029] In some embodiments, the plug comprises a first conducting segment, a second conducting segment, a third conducting segment and a fourth conducting segment, the first signal line comprises a first sub-signal line and a second sub-signal line, and the second signal line comprises a third sub-signal line and a fourth sub-signal line; wherein the first sub-signal line, the second sub-signal line, the third sub-signal line and the fourth sub-signal line are respectively electrically connected with the first conducting segment, the second conducting segment, the third conducting segment and the fourth conducting segment; in the case that the first conducting segment is short-circuited with the third conducting segment, the first sub-signal line is conducted with the third sub-signal line; and in the case that the second conducting segment is short-circuited with the fourth conducting segment, the second sub-signal line is conducted with the fourth sub-signal line.

[0030] In this embodiment, the plug, the first signal line and the second signal line are limited. The first signal line comprises a first sub-signal line and a second sub-signal line, the second signal line comprises a third sub-signal line and a fourth sub-signal line, the plug comprises a plurality of conducting segments, and the plurality of conducting segments are respectively electrically connected with the first sub-signal line, the second sub-signal line, the third sub-signal line and the fourth sub-signal line. In this way, the first signal line and the second signal line can be conducted in the case that part of the plurality of conducting segments are short-circuited.

[0031] Specifically, the plug comprises a first conducting segment, a second conducting segment, a third conducting segment and a fourth conducting segment, and the first sub-signal line, the second sub-signal line, the third sub-signal line and the fourth sub-signal line are respectively electrically connected with the first conducting segment, the second conducting segment, the third conducting segment and the fourth conducting segment. In the case that the first conducting segment is short-circuited with the third conducting segment, the first sub-signal line is conducted with the third sub-signal line, so as to conduct the first signal line and the second signal line. In the case that the second conducting segment is short-circuited with the fourth conducting segment, the second sub-signal line is conducted with the fourth sub-signal line, so as to conduct the first signal line and the second signal line.

[0032] In some embodiments, the temperature probe further comprises a connecting line and a protective layer. The connecting line is used for electrically connecting the first signal line and the second signal line with the plug respectively, and the protective layer is wrapped outside the connecting line and is capable of insulation.

[0033] In the technical solution, the structure of the temperature probe is further limited. The temperature probe further comprises a connecting piece, and the connecting line is used to electrically connect the first signal line and the second signal line with the plug respectively. Specifically, the connecting line is made of conductive material, and the first signal line, the second signal line and the plug are electrically connected with the connecting line, so as to realize the electrical connection of the first signal line and the second signal line with the plug. The connecting line has a certain flexibility, so as to facilitate the bending of the temperature probe in the cooking cavity and facilitate the use of the user.

[0034] Further, in order to protect the connecting line and prevent the connecting line from leaking, the connecting line is further covered with a protective layer made of insulating material. In this way, on the one hand, the connecting line can be protected by the protective layer to avoid damage to the connecting line caused by water vapor in the cooking cavity, and on the other hand, the connecting line can be insulated from the outside by the protective layer, preventing the connecting line from leaking. The protective layer can be made of silicone rubber.

[0035] In some technical solutions, the temperature probe further comprises a second handle connected to the plug, and the connecting line passes through the second handle and is electrically connected with the plug. The second handle can be insulated and heat insulated.

[0036] In the technical solution, the structure of the temperature probe is further limited, and the temperature probe further comprises a second handle connected to the plug. When the user needs to connect or separate the plug and the probe socket, the user can hold the second handle to connect or separate the plug. By providing the second handle connected to the plug in the temperature probe, the user's convenience of use can be improved.

[0037] Further, the connecting line passes through the second handle and is electrically connected with the plug, so that the connecting line can normally transmit the first temperature signal and the second temperature signal.

[0038] Further, the second handle is made of insulating and heat insulating material, so that on the one hand, the temperature of the second handle can be prevented from being too high to avoid scalding the user, and on the other hand, the phenomenon of leakage of the connecting line can be avoided. The second handle can be made of silicone rubber.

[0039] By providing the second handle connected to the plug in the temperature probe, the user can operate the plug through the second handle, thereby improving the user's convenience of use.

[0040] The second aspect of the utility model further provides a cooking utensil, which comprises: a box body having a cooking cavity; a temperature control device arranged on the box body, the temperature control device being used for adjusting the temperature in the cooking cavity; a temperature detection device arranged on the box body, the temperature detection device being used for detecting the temperature in the cooking cavity and being electrically connected with the temperature control device; and a probe socket arranged on the box body and electrically connected with the temperature control device. The temperature probe provided by the first aspect of the utility model is detachably connected with the probe socket. The temperature control device can adjust the temperature in the cooking cavity according to the detection results of the temperature detection device and / or the temperature probe.

[0041] The cooking utensil provided by the utility model comprises a box body, a temperature control device and a temperature detection device. The box body comprises a cooking cavity, and the cooking cavity is used for accommodating food materials. The temperature control device is arranged on the box body. When the cooking utensil heats the food materials, the temperature in the cooking cavity needs to be adjusted, and the temperature control device is used for adjusting the temperature in the cooking cavity. The temperature detection device is arranged on the box body, and specifically, the temperature detection device is arranged on the wall surface of the cooking cavity and located in the cooking cavity. The temperature detection device is used for detecting the temperature in the cooking cavity. The temperature detection device is electrically connected with the temperature control device. The temperature detection device can convert the detection results into signals and send the signals to the temperature control device. The temperature control device can adjust the temperature in the cooking cavity according to the detection results of the temperature detection device.

[0042] Understandably, since the temperature detection device is far away from the center of the cooking cavity, when the volume of the food materials in the cooking cavity is large, the temperature detected by the temperature detection device is the temperature close to the wall surface of the cooking cavity, which is greatly different from the temperature at the center of the cooking cavity. If the temperature control device only adjusts the temperature according to the detection results of the temperature detection device, the temperature adjustment effect is poor. Therefore, the temperature probe and the probe socket are further arranged in the cooking utensil, so that the temperature control device can also adjust the temperature according to the detection results of the temperature probe. The probe socket is arranged on the box body and electrically connected with the temperature control device. The temperature probe is detachably connected with the probe socket. When the temperature in the cooking cavity needs to be collected by the temperature probe, the user connects the temperature probe with the probe socket. At this time, the temperature probe can be electrically connected with the temperature control device. The temperature probe can convert the detection results into signals and send the signals to the temperature control device. The temperature control device adjusts the temperature according to the detection results of the temperature probe. When the user does not need to collect the temperature in the cooking cavity by the temperature probe, the user can separate the temperature probe from the probe socket. The probe socket is arranged on the inner wall of the cooking cavity, so as to facilitate the user to connect the temperature probe with the probe socket.

[0043] The cooking utensil provided by the second aspect of the utility model comprises the temperature probe provided by the first aspect of the utility model, and therefore has all the beneficial effects of the temperature probe.

[0044] The cooking utensil can be an oven, a steaming and baking oven or a micro-oven integrated machine.

[0045] In some technical solutions, the second temperature sensor of the temperature probe detects a first temperature value when the temperature probe is connected with the probe socket; the temperature control device operates according to the difference between the first temperature value and the target temperature; or the temperature control device operates according to the detection result of the temperature detection device, the second temperature value is detected by the temperature detection device, if the difference between the second temperature value and the target temperature is greater than a preset threshold, the third temperature value is detected by the second temperature sensor, the temperature control device operates according to the difference between the third temperature value and the target temperature, if the difference between the second temperature value and the target temperature is less than or equal to the preset threshold, the temperature control device continues to operate according to the detection result of the temperature detection device.

[0046] In this technical solution, the cooking appliance is further limited. The temperature probe has a second temperature sensor, when the temperature probe is connected with the probe socket, the temperature probe can be inserted into the food material, the second temperature sensor is located outside the food material, so the ambient temperature around the food material can be detected by the second temperature sensor, and the second temperature sensor can generate a second temperature signal. After the temperature probe is connected with the probe socket, the second temperature signal generated by the second temperature sensor is received, and a first temperature value is obtained, the first temperature value is the ambient temperature value around the food material, since the second temperature sensor is relatively close to the center of the cooking cavity, the first temperature value can accurately reflect the temperature of the center of the cooking cavity. Then the cooking appliance can be controlled by two different technical solutions.

[0047] In one possible technical solution, the temperature control device operates according to the difference between the first temperature value and the target temperature. That is, the temperature control device does not operate according to the detection result of other temperature detection devices, but directly operates according to the detection result of the temperature probe.

[0048] In another possible technical solution, the cooking utensil further has a temperature detection device for detecting the temperature of the cooking cavity, the temperature detection device being arranged on a wall surface of the cooking cavity and extending into the cooking cavity so that the temperature detection device can detect the temperature in the cooking cavity. However, since the temperature detection device is far away from the center of the cooking cavity, when the volume of the food material is large, the detection result of the temperature detection device greatly differs from the actual temperature at the center of the cooking cavity. First, the temperature control device of the cooking utensil is controlled to operate according to the detection result of the temperature detection device of the cooking utensil. After the temperature in the cooking cavity is raised, a second temperature value is obtained according to the detection result of the temperature detection device. The second temperature value is compared with the target temperature, and if the difference between the target temperature and the second temperature value is greater than a preset threshold value, it is indicated that the detection result of the temperature detection device is inaccurate, and then the temperature control is performed according to the detection result of the temperature probe. Specifically, a third temperature value is obtained according to the detection result of the second temperature sensor, and the temperature control device operates according to the difference between the third temperature value and the target temperature. If the difference between the target temperature and the second temperature is less than or equal to the preset threshold value, it is indicated that the detection result of the temperature detection device meets the requirement, and the temperature control device operates according to the detection result of the temperature detection device.

[0049] Since the second temperature sensor in the temperature probe is closer to the center of the cooking cavity, a temperature value closer to the center of the cooking cavity can be obtained, so that the cooking utensil can accurately obtain the temperature at the center of the cooking cavity even when the volume of the food material is large. The present application improves the temperature control precision by controlling the temperature control device according to the detection result of the second temperature sensor, thereby improving the temperature recovery speed in the cooking cavity and the cooking effect of the cooking utensil. The additional aspects and advantages of the present application will become apparent from the following description, or will be appreciated by practice of the present application.

[0063] In one embodiment according to the present application, as Figure 1 , Figure 2 And Figure 3As shown, the present application proposes a temperature probe 100, the temperature probe 100 is used in a cooking appliance 200, the cooking appliance 200 comprises a cooking cavity 211 for accommodating foodstuff, the temperature probe 100 comprises: a first probe part 110 for detecting the temperature of the foodstuff, the first probe part 110 comprises: a probe body 111, at least a part of the probe body 111 is used for inserting into the foodstuff, the probe body 111 has a first end 113 and a second end 114 which are away from each other, the first end 113 can be inserted into the foodstuff; at least one first temperature sensor 112 is arranged on the probe body 111, the first temperature sensor 112 is close to the first end 113, the first temperature sensor 112 is used for detecting the temperature of the foodstuff; at least one second temperature sensor 120 is used for detecting the temperature of the cooking cavity 211; wherein the second temperature sensor 120 is arranged on the probe body 111, the probe body 111 has a limiting line 115, the limiting line 115 is used for indicating the depth of the probe body 111 inserted into the foodstuff, the first temperature sensor 112 is located on one side of the limiting line 115 which is towards the first end 113, and the second temperature sensor 120 is located on one side of the limiting line 115 which is towards the second end 114; and / or the temperature probe 100 further comprises: a second probe part 130, the second probe part 130 is close to the second end 114, in the case that the first probe part 110 is inserted into the foodstuff, the second probe part 130 can have a spacing with the foodstuff, and the second temperature sensor 120 is arranged on the second probe part 130.

[0064] The temperature probe 100 proposed by the present application can be applied in the cooking appliance 200. The cooking appliance 200 to which the temperature probe 100 is applied has a cooking cavity 211 for accommodating foodstuff, and the temperature probe 100 can be inserted into the foodstuff and detect the temperature of the foodstuff and the ambient temperature around the foodstuff.

[0065] The temperature probe 100 comprises a first probe part 110, at least a part of the first probe part 110 can be inserted into the foodstuff and detect the temperature inside the foodstuff. The first probe part 110 comprises a probe body 111 and a first temperature sensor 112, at least a part of the probe body 111 can be inserted into the foodstuff when detecting the temperature by the temperature probe 100, and the first temperature sensor 112 is arranged on the probe body 111, when the probe body 111 is inserted into the foodstuff, the first temperature sensor 112 extends into the foodstuff together with the probe body 111, so that the temperature inside the foodstuff can be detected by the first temperature sensor 112. Specifically, the probe body 111 has a first end 113 and a second end 114 which are away from each other, the first end 113 can be inserted into the foodstuff, and the first temperature sensor 112 is close to the first end 113. In this way, the first temperature sensor 112 can be inserted to a position closer to the center of the foodstuff, so as to improve the accuracy of the temperature detection of the foodstuff by the first temperature sensor 112.

[0066] Further, the width of the probe body 111 gradually decreases in the direction towards the first end 113 of the probe body 111, and the first end 113 of the probe body 111 is in a pointed structure, so that the probe body 111 can be more easily inserted into the food material. The number of the first temperature sensor 112 can be one or multiple. When the number of the first temperature sensor 112 is multiple, the multiple first temperature sensors 112 can be arranged in sequence along the length direction of the probe body 111, or can be arranged at the same position along the length direction of the probe body 111. The first temperature sensor 112 can be arranged inside the probe body 111, i.e. the first temperature sensor 112 is not exposed outside the probe body 111, so that the first temperature sensor 112 can be protected by the probe body 111. The probe body 111 can transmit heat, and the heat of the food material can be transmitted to the first temperature sensor 112 through the probe body 111. The first temperature sensor 112 can also be arranged on the surface of the probe body 111 to improve the detection accuracy of the first temperature sensor 112. The probe body 111 can be made of stainless steel.

[0067] Further, in order to detect the ambient temperature around the food material, the present application also provides a second temperature sensor 120 in the temperature probe 100, and when at least a part of the probe body 111 is inserted into the food material, the second temperature sensor 120 is located outside the food material, so that the ambient temperature around the food material in the cooking cavity 211 can be detected by the second temperature sensor 120.

[0068] As Figure 1As shown, in one possible embodiment, the temperature probe 100 further includes a second probe portion 130, which is located near the second end 114 of the probe body 111. That is, when the probe body 111 is inserted into the food, the second probe portion 130 is located on the side of the probe body 111 away from the food. This allows the second probe portion 130 to maintain a gap with the food when the first probe portion 110 is inserted. A second temperature sensor 120 is disposed within the second probe portion 130. Specifically, the second temperature sensor 120 is located inside the second probe portion 130. When at least a portion of the probe body 111 is inserted into the food, there is a gap between the second probe portion 130 and the food, thus placing the second temperature sensor 120 outside the food. The second probe portion 130 is made of a material with excellent thermal conductivity to conduct heat, transferring heat from the surrounding environment to the second temperature sensor 120, enabling the second temperature sensor 120 to detect the ambient temperature around the food. Furthermore, compared to the temperature detection component located on the wall of the cooking cavity 211, the second temperature sensor 120 is closer to the center of the cooking cavity 211, so the temperature detection result of the second temperature sensor 120 is more accurate.

[0069] like Figure 2 As shown, in another possible embodiment, the second temperature sensor 120 is disposed on the probe body 111. The probe body 111 has a limiting line 115, which is close to the second end 114 of the probe body 111. The limiting line 115 is used to indicate the depth to which the probe body 111 is inserted into the food. Specifically, when the user inserts the probe body 111 into the food, the insertion depth of the probe body 111 can be observed through the limiting line 115, keeping the limiting line 115 outside the food, or the probe body 111 can be inserted into the position of the limiting line 115. The first temperature sensor 112 and the second temperature sensor 120 are respectively located on both sides of the limiting line 115. The first temperature sensor 112 is located on the side of the limiting line 115 facing the first end 113, and the second temperature sensor 120 is located on the side of the limiting line 115 facing the second end 114. When the probe body 111 is inserted into the food, the second temperature sensor 120 is located on the side of the limiting line 115 facing the second end 114, allowing the second temperature sensor 120 to be positioned outside the food. Compared to a structure where the second temperature sensor 120 is located on the second probe portion 130, placing the second temperature sensor 120 on the probe body 111 allows the second temperature sensor 120 to be closer to the food, thereby making the temperature value detected by the second temperature sensor 120 closer to the temperature at the center of the cooking cavity 211, and making the temperature detection result of the second temperature sensor 120 more accurate.

[0070] By arranging the first temperature sensor 112 and the second temperature sensor 120 in the temperature probe 100, and arranging the second temperature sensor 120 outside the food material, the temperature inside the food material can be detected by the first temperature sensor 112, and the ambient temperature around the food material can be detected by the second temperature sensor 120. Compared with the temperature detection component arranged on the wall of the cooking cavity 211, the second temperature sensor 120 is closer to the center of the cooking cavity 211, so that the temperature value closer to the center of the cooking cavity 211 can be obtained, and the accuracy of temperature detection of the temperature probe 100 is improved. Therefore, the cooking appliance 200 can obtain the temperature at the center of the cooking cavity 211 more accurately even when the volume of the food material is large, so that the cooking appliance 200 can control the temperature more accurately, improve the temperature recovery speed in the cooking cavity 211, and improve the cooking effect of the cooking appliance 200.

[0071] In some embodiments, as shown in FIGS. 1 and 2, the temperature probe 100 further comprises a first handle 140. The second end 114 of the first probe portion 110 is connected to one end of the first handle 140. In the case that the temperature probe 100 comprises the second probe portion 130, the second probe portion 130 is connected to the other end of the first handle 140. The first handle 140 is insulated and heat-insulated. Figure 1 and Figure 2 In some embodiments, as shown in FIGS. 1 and 2, the temperature probe 100 further comprises a first handle 140. The second end 114 of the first probe portion 110 is connected to one end of the first handle 140. In the case that the temperature probe 100 comprises the second probe portion 130, the second probe portion 130 is connected to the other end of the first handle 140. The first handle 140 is insulated and heat-insulated.

[0072] In this embodiment, the structure of the temperature probe 100 is further limited. The temperature probe 100 further comprises a first handle 140. On the one hand, the first handle 140 facilitates the user to hold the temperature probe 100. On the other hand, the first handle 140 can block the first probe portion 110 and the second probe portion 130. The first handle 140 has two different arrangement positions based on the arrangement position of the second temperature sensor 120. In the case that the second temperature sensor 120 is arranged in the second probe portion 130, the temperature probe 100 comprises the second probe portion 130, and the second end 114 of the first probe portion 110 and the second probe portion 130 are connected to the two ends of the first handle 140, respectively. In the case that the second temperature sensor 120 is arranged in the probe body 111, the first handle 140 is connected to the second end 114 of the first probe portion 110.

[0073] Specifically, the first handle 140 is made of an insulating and heat-insulated material, such as silicone rubber. In this way, the first handle 140 can be prevented from electric leakage, and the temperature of the first handle 140 can be prevented from being too high, so that the user can hold the temperature probe 100 more conveniently. Further, since the first handle 140 is made of an insulating and heat-insulated material, the first handle 140 can block the heat conduction between the probe body 111 and the second probe portion 130, so that the temperature detection of the first temperature sensor 112 and the second temperature sensor 120 is not affected, and the temperature detection accuracy of the temperature probe 100 is improved.

[0074] In some embodiments, the first probe portion 110 further comprises a heat-conducting member arranged in the probe body 111 and in contact with the first temperature sensor 112, the heat-conducting member being capable of conducting heat.

[0075] In this embodiment, the structure of the first probe portion 110 is further limited. In order to improve the heat conduction effect of the probe body 111, the present application further provides a heat-conducting member in the first probe portion 110. Specifically, the heat-conducting member is made of a heat-conducting material with excellent heat conduction, so that the heat-conducting member can conduct heat. The heat-conducting member is arranged in the probe body 111 and in contact with the first temperature sensor 112. Understandably, when the first temperature sensor 112 is arranged in the probe body 111, the probe body 111 transmits the heat of the food to the first temperature sensor 112, so that the first temperature sensor 112 can detect the temperature in the food. If the heat conduction effect of the probe body 111 is poor, the detection accuracy of the first temperature sensor 112 will be reduced. In order to avoid this problem, the present application provides a heat-conducting member in the probe body 111. The heat-conducting member can be made of a material with excellent heat conduction effect, such as resin. The heat-conducting member is in contact with both the probe body 111 and the first temperature sensor 112, so that the probe body 111 transmits heat to the first temperature sensor 112 through the heat-conducting member. Since the heat-conducting member has excellent heat conduction, it can improve the heat transfer speed and reduce heat loss, thereby improving the temperature measurement speed and accuracy of the first temperature sensor 112. The heat-conducting member can be filled in the probe body 111.

[0076] By arranging the heat-conducting member in contact with the first temperature sensor 112 in the probe body 111, heat can be transmitted to the first temperature sensor 112 through the heat-conducting member, thereby improving the temperature measurement speed and accuracy of the first temperature sensor 112.

[0077] In some embodiments, the probe body 111 and the second probe portion 130 are both metal components.

[0078] In this embodiment, the probe body 111 and the second probe part 130 are further defined. Specifically, the probe body 111 and the second probe part 130 are made of a metal material. When the first temperature sensor 112 is arranged inside the probe body 111, heat needs to be transmitted to the first temperature sensor 112 through the probe body 111. When the second temperature sensor 120 is arranged in the second probe part 130, the second temperature sensor 120 can be located inside the second probe part 130, and in this case, heat needs to be transmitted to the second temperature sensor 120 through the second probe part 130. By arranging the probe body 111 and the second probe part 130 to be made of a metal material, the probe body 111 and the second probe part 130 can have excellent heat conductivity, so as to improve the temperature measurement accuracy of the first temperature sensor 112 and the second temperature sensor 120.

[0079] In some embodiments, as shown in FIGS. 1A and 1B, the temperature probe 100 further comprises a first signal line 116 and a second signal line 131. Figure 1 and Figure 2 As shown in FIGS. 1A and 1B, the cooking utensil 200 further comprises a temperature control device for adjusting the temperature in the cooking cavity 211. The temperature probe 100 further comprises: the first signal line 116 connected with the first temperature sensor 112, the first temperature sensor 112 being capable of generating a first temperature signal when detecting the temperature of the food material, the first signal line 116 being used for transmitting the first temperature signal; and the second signal line 131 connected with the second temperature sensor 120, the second temperature sensor 120 being capable of generating a second temperature signal when detecting the temperature of the cooking cavity 211, the second signal line 131 being used for transmitting the second temperature signal; wherein the first signal line 116 and the second signal line 131 are electrically connected with the temperature control device.

[0080] In this embodiment, the structure of the temperature probe 100 is further defined. The cooking utensil 200 has a temperature control device for adjusting the temperature in the cooking cavity 211. When the cooking utensil 200 heats the food material, the temperature probe 100 detects the temperature of the food material and the environment around the food material. After the first temperature sensor 112 and the second temperature sensor 120 respectively detect the temperature in the food material and the temperature of the environment around the food material, the temperature values detected by the first temperature sensor 112 and the second temperature sensor 120 need to be converted into signals and sent to the temperature control device. In order to send the signals generated by the first temperature sensor 112 and the second temperature sensor 120 to the temperature control device, the first signal line 116 and the second signal line 131 are further arranged in the temperature probe 100.

[0081] Specifically, the first signal line 116 is connected with the first temperature sensor 112, the first temperature sensor 112 is capable of generating a first temperature signal when detecting the temperature of the food material, and the first signal line 116 is used for transmitting the first temperature signal. The second signal line 131 is connected with the second temperature sensor 120, the second temperature sensor 120 is capable of generating a second temperature signal when detecting the temperature of the cooking cavity 211, and the second signal line 131 is used for transmitting the second temperature signal. Further, the first signal line 116 and the second signal line 131 are both capable of being electrically connected with the temperature control device, so that the first temperature signal and the second temperature signal can be transmitted to the temperature control device through the first signal line 116 and the second signal line 131 respectively, so that the temperature control device can adjust the temperature in the cooking cavity 211 according to the detection results of the first temperature sensor 112 and the second temperature sensor 120.

[0083] In this embodiment, the structure of the temperature probe 100 is further limited. The cooking appliance 200 includes a box body 210, the box body 210 has a probe socket 230, and the temperature probe 100 is detachably connected with the probe socket 230. When the user needs to detect the temperature in the cooking cavity 211 through the temperature probe 100, the user can connect the temperature probe 100 with the probe socket 230, and when the user does not need to use the temperature probe 100, the temperature probe 100 can be separated from the probe socket 230. The temperature probe 100 includes a plug 150, the plug 150 can be separably connected with the probe socket 230, so as to realize the connection and separation of the temperature probe 100 and the probe socket 230.

[0084] Specifically, the first signal line 116 and the second signal line 131 are respectively electrically connected with the plug 150, the plug 150 can be connected with the probe socket 230, and when the plug 150 is connected with the probe socket 230, the electrical connection between the plug 150 and the temperature control device can be realized due to the electrical connection between the probe socket 230 and the temperature control device. In this way, the temperature probe 100 can transmit the first temperature signal and the second temperature signal to the temperature control device, so that the temperature control device can adjust the temperature in the cooking cavity 211 according to the detection results of the first temperature sensor 112 and the second temperature sensor 120.

[0086] In this embodiment, the plug 150, the first signal line 116, and the second signal line 131 are defined. The first signal line 116 includes a first sub-signal line 117 and a second sub-signal line 118, the second signal line 131 includes a third sub-signal line 132 and a fourth sub-signal line 133, and the plug 150 includes a plurality of conducting segments electrically connected with the first sub-signal line 117, the second sub-signal line 118, the third sub-signal line 132, and the fourth sub-signal line 133 respectively, so that the first signal line 116 and the second signal line 131 can be in conduction in the case of short-circuiting between some of the plurality of conducting segments.

[0087] Specifically, the plug 150 includes a first conducting segment, a second conducting segment 151, a third conducting segment, and a fourth conducting segment 152, and the first sub-signal line 117, the second sub-signal line 118, the third sub-signal line 132, and the fourth sub-signal line 133 are electrically connected with the first conducting segment, the second conducting segment 151, the third conducting segment, and the fourth conducting segment 152 respectively. In the case of short-circuiting between the first conducting segment and the third conducting segment, the first sub-signal line 117 is in conduction with the third sub-signal line 132 to make the first signal line 116 and the second signal line 131 in conduction. In the case of short-circuiting between the second conducting segment 151 and the fourth conducting segment 152, the second sub-signal line 118 is in conduction with the fourth sub-signal line 133 to make the first signal line 116 and the second signal line 131 in conduction.

[0088] In some embodiments, as shown in Figure 1 and Figure 2 As shown, the temperature probe 100 further includes a connecting line 160 for electrically connecting the first signal line 116 and the second signal line 131 with the plug 150 respectively, and a protective layer covering the outside of the connecting line 160, which is capable of insulation.

[0089] In this embodiment, the structure of the temperature probe 100 is further limited. The temperature probe 100 further comprises a connecting line 160 for electrically connecting the first signal line 116 and the second signal line 131 with the plug 150 respectively. Specifically, the connecting line 160 is made of an electrically conductive material, and the first signal line 116, the second signal line 131 and the plug 150 are all electrically connected with the connecting line 160, so as to realize the electrical connection between the first signal line 116, the second signal line 131 and the plug 150. The connecting line 160 has a certain flexibility, so as to facilitate the bending of the temperature probe 100 in the cooking cavity 211, and facilitate the use of the user.

[0090] Further, in order to protect the connecting line 160 and prevent the connecting line 160 from electric leakage, an insulating layer is further coated outside the connecting line 160. In this way, on the one hand, the connecting line 160 can be protected by the insulating layer to avoid damage to the connecting line 160 caused by the water vapor in the cooking cavity 211, and on the other hand, the connecting line 160 can be insulated from the outside by the insulating layer, so as to prevent the connecting line 160 from electric leakage. The insulating layer can be made of silicone rubber.

[0091] In some embodiments, optionally, as shown in Figure 1 and Figure 2 The temperature probe 100 further comprises a second handle 170 connected to the plug 150, and the connecting line 160 passes through the second handle 170 and is electrically connected with the plug 150, and the second handle 170 can be insulated and heat insulated.

[0092] In this embodiment, the structure of the temperature probe 100 is further limited, and the temperature probe 100 further comprises a second handle 170 connected with the plug 150. When the user needs to connect or separate the plug 150 with the probe socket 230, the user can take the second handle 170 to perform the operation of connecting or separating the plug 150. By providing the second handle 170 connected with the plug 150 in the temperature probe 100, the convenience of use of the user can be improved.

[0093] Further, the connecting line 160 passes through the second handle 170 and is electrically connected with the plug 150, so that the connecting line 160 can normally transmit the first temperature signal and the second temperature signal.

[0094] Further, the second handle 170 is made of an insulating and heat insulating material, so that on the one hand, the temperature of the second handle 170 can be prevented from being too high to scald the user, and on the other hand, the electric leakage of the connecting line 160 can also be avoided. The second handle 170 can be made of silicone rubber.

[0095] By arranging the second handle 170 connected with the plug 150 in the temperature probe 100, the user can operate the plug 150 through the second handle 170, thereby improving the user's convenience.

[0096] As Figure 1 shown, the second aspect of the utility model further provides a cooking utensil 200, include: box 210 have cooking cavity 211, temperature control device is located in box 210, temperature control device is used for adjusting the temperature in cooking cavity 211, temperature detection device 220 is located in box 210, temperature detection device 220 is used for detecting the temperature in cooking cavity 211 and is electrically connected with temperature control device, probe socket 230 is located in box 210, and probe socket 230 is electrically connected with temperature control device, the temperature probe 100 proposed in any one embodiment of the above is detachably connected in probe socket 230, wherein temperature control device can adjust the temperature in cooking cavity 211 according to the detection result of temperature detection device 220 and / or temperature probe 100.

[0097] The application provides a cooking utensil 200, which comprises a box body 210, a temperature control device and a temperature detection device 220. The box body 210 comprises a cooking cavity 211 for accommodating food materials. The temperature control device is arranged on the box body 210. When the cooking utensil 200 heats the food materials, the temperature in the cooking cavity 211 needs to be adjusted, and the temperature control device is used to adjust the temperature in the cooking cavity 211. The temperature detection device 220 is arranged on the box body 210, specifically, on the wall of the cooking cavity 211 and in the cooking cavity 211. The temperature detection device 220 is used to detect the temperature in the cooking cavity 211. The temperature detection device 220 is electrically connected with the temperature control device. The temperature detection device 220 can convert the detection result into a signal and send the signal to the temperature control device. The temperature control device can adjust the temperature in the cooking cavity 211 according to the detection result of the temperature detection device 220.

[0098] Understandably, since the temperature detection device 220 is away from the center of the cooking cavity 211, when the volume of the food in the cooking cavity 211 is large, the temperature detected by the temperature detection device 220 is the temperature close to the wall surface of the cooking cavity 211, which is greatly different from the temperature at the center of the cooking cavity 211, and if the temperature control device only controls the temperature according to the detection result of the temperature detection device 220, the temperature regulation effect will be poor. Therefore, the present application also provides a temperature probe 100 and a probe socket 230 in the cooking appliance 200, so that the temperature control device can also control the temperature according to the detection result of the temperature probe 100. The probe socket 230 is arranged in the box body 210, and the probe socket 230 is electrically connected with the temperature control device. The temperature probe 100 is detachably connected with the probe socket 230. When it is needed to collect the temperature in the cooking cavity 211 through the temperature probe 100, the user connects the temperature probe 100 with the probe socket 230, at this time the temperature probe 100 can be electrically connected with the temperature control device, and the temperature probe 100 can convert the detection result into a signal and send it to the temperature control device, and the temperature control device controls the temperature according to the detection result of the temperature probe 100. When the user does not need to collect the temperature in the cooking cavity 211 through the temperature probe 100, the user can separate the temperature probe 100 from the probe socket 230. The probe socket 230 is arranged on the inner wall of the cooking cavity 211, so as to facilitate the user to connect the temperature probe 100 with the probe socket 230.

[0099] The cooking appliance 200 provided in the second aspect of the present application comprises the temperature probe 100 provided in any one of the above embodiments, and therefore has all the beneficial effects of the temperature probe 100.

[0100] The cooking appliance 200 can be an oven, a steaming oven or a micro-oven integrated machine.

[0101] In some embodiments, optionally, when the temperature probe 100 is connected with the probe socket 230, the second temperature sensor 120 of the temperature probe 100 detects a first temperature value; the temperature control device operates according to the difference between the first temperature value and a target temperature; or the temperature control device operates according to the detection result of the temperature detection device 220, the temperature detection device 220 detects a second temperature value, if the difference between the second temperature value and the target temperature is greater than a preset threshold value, the second temperature sensor 120 detects a third temperature value, and the temperature control device operates according to the difference between the third temperature value and the target temperature, if the difference between the second temperature value and the target temperature is less than or equal to the preset threshold value, the temperature control device continues to operate according to the detection result of the temperature detection device 220.

[0102] In this embodiment, the cooking appliance 200 is further defined. The temperature probe 100 has a second temperature sensor 120. When the temperature probe 100 is connected to the probe socket 230, the temperature probe 100 can be inserted into food. The second temperature sensor 120 is located outside the food, thus it can detect the ambient temperature around the food and generate a second temperature signal. After the temperature probe 100 is connected to the probe socket 230, it receives the second temperature signal generated by the second temperature sensor 120 to obtain a first temperature value. The first temperature value is the ambient temperature around the food. Since the second temperature sensor 120 is relatively close to the center of the cooking cavity, the first temperature value can accurately reflect the temperature at the center of the cooking cavity. The cooking appliance 200 can then be controlled using two different technical solutions.

[0103] In one possible embodiment, the temperature control device operates based on the difference between a first temperature value and a target temperature. That is, the temperature control device operates directly based on the detection results of the temperature probe 100, rather than on the detection results of other temperature detection devices 220.

[0104] In another possible embodiment, the cooking appliance 200 also has a temperature detection device 220 for detecting the temperature of the cooking cavity. The temperature detection device 220 is disposed on the wall of the cooking cavity and extends into the cooking cavity so that it can detect the temperature inside the cooking cavity. However, since the temperature detection device 220 is far from the center of the cooking cavity, when the volume of the food is large, the detection result of the temperature detection device 220 differs significantly from the actual temperature at the center of the cooking cavity. First, the temperature control device of the cooking appliance 200 is controlled based on the detection result of the temperature detection device 220. After the temperature inside the cooking cavity rises, a second temperature value is obtained based on the detection result of the temperature detection device 220. The second temperature value is compared with a target temperature. If the difference between the target temperature and the second temperature value is greater than a preset threshold, it indicates that the detection result of the temperature detection device 220 is inaccurate. Then, temperature control is performed based on the detection result of the temperature probe 100. Specifically, a third temperature value is obtained based on the detection result of the second temperature sensor 120, and the temperature control device operates based on the difference between the third temperature value and the target temperature. If the difference between the target temperature and the second temperature is less than or equal to the preset threshold, it means that the detection result of the temperature detection device 220 meets the requirements, and the temperature control device operates according to the detection result of the temperature detection device 220.

[0105] Since the second temperature sensor 120 in the temperature probe 100 is closer to the center of the cooking cavity, the temperature value closer to the center of the cooking cavity can be obtained, so that the cooking appliance 200 can obtain the temperature at the center of the cooking cavity more accurately even when the volume of the food material is large. The present application improves the temperature control precision by controlling the temperature control device according to the detection result of the second temperature sensor 120, thereby improving the temperature recovery speed in the cooking cavity and the cooking effect of the cooking appliance 200. The third aspect of the present application also provides a control method of a cooking appliance, which is used for the cooking appliance provided in any of the above embodiments, as shown in Figure 2 The control method of the cooking appliance provided in the embodiments of the present application includes the following steps S102 to S114:

[0106] S102: receiving an insertion signal of the temperature probe and confirming that the temperature probe is connected to the probe socket of the cooking appliance;

[0107] S104: obtaining a first temperature value according to the detection result of the second temperature sensor of the temperature probe;

[0108] S106: controlling the temperature control device of the cooking appliance to operate according to the difference between the first temperature value and the target temperature;

[0109] S108: controlling the temperature control device of the cooking appliance to operate according to the detection result of the temperature detection device of the cooking appliance;

[0110] S110: obtaining a second temperature value according to the detection result of the temperature detection device of the cooking appliance;

[0111] S112: comparing the second temperature value with the target temperature, if the difference between the target temperature and the second temperature value is greater than a preset threshold, step S114 is performed, and if the difference between the target temperature and the second temperature is less than or equal to the preset threshold, step S108 is performed;

[0112] S114: obtaining a third temperature value according to the detection result of the second temperature sensor, and controlling the temperature control device of the cooking appliance to operate according to the difference between the third temperature value and the target temperature.

[0113] The application provides a control method of a cooking appliance. The control method can be used in the cooking appliance provided in the foregoing embodiments. The cooking appliance comprises a box body having a cooking cavity, a probe socket and a temperature probe. The temperature probe is detachably connected to the probe socket. When the temperature probe is connected to the probe socket, the temperature probe can detect the temperature in the cooking cavity. When the cooking appliance is in operation, firstly, an insertion signal of the temperature probe is received to confirm that the temperature probe is connected to the probe socket. The temperature probe is provided with a second temperature sensor. When the temperature probe is inserted into food, the second temperature sensor is located outside the food, so that the ambient temperature around the food can be detected by the second temperature sensor, and the second temperature sensor can generate a second temperature signal. After confirming that the temperature probe is connected to the probe socket, the second temperature signal generated by the second temperature sensor is received to obtain a first temperature value, which is the ambient temperature value around the food. Since the second temperature sensor is relatively close to the center of the cooking cavity, the first temperature value can accurately reflect the temperature at the center of the cooking cavity. Then the cooking appliance can be controlled by two different embodiments.

[0114] In a possible embodiment, the temperature control device is controlled to operate according to the difference between the first temperature value and the target temperature. That is, the temperature control device is directly controlled to operate according to the detection result of the temperature probe without the detection result of other temperature detection devices.

[0115] In another possible embodiment, the cooking appliance is further provided with a temperature detection device for detecting the temperature in the cooking cavity. The temperature detection device is arranged on the wall of the cooking cavity and extends into the cooking cavity, so that the temperature detection device can detect the temperature in the cooking cavity. However, since the temperature detection device is far away from the center of the cooking cavity, when the volume of the food is large, the detection result of the temperature detection device is greatly different from the actual temperature at the center of the cooking cavity. Firstly, the temperature control device of the cooking appliance is controlled to operate according to the detection result of the temperature detection device of the cooking appliance. After the temperature in the cooking cavity is increased, a second temperature value is obtained according to the detection result of the temperature detection device of the cooking appliance. The second temperature value is compared with the target temperature. If the difference between the target temperature and the second temperature value is greater than a preset threshold value, it indicates that the detection result of the temperature detection device is inaccurate, and then the temperature control is performed according to the detection result of the temperature probe. Specifically, a third temperature value is obtained according to the detection result of the second temperature sensor, and the temperature control device is controlled to operate according to the difference between the third temperature value and the target temperature. If the difference between the target temperature and the second temperature value is less than or equal to the preset threshold value, it indicates that the detection result of the temperature detection device meets the requirement, and then the temperature control device of the cooking appliance is controlled to operate according to the detection result of the temperature detection device.

[0116] Because the second temperature sensor in the temperature probe is closer to the center of the cooking cavity, it can obtain a temperature value closer to the center of the cooking cavity. This allows the cooking appliance to accurately measure the temperature at the center of the cooking cavity even when the food is large. This application improves temperature control accuracy, increases the rate of temperature recovery within the cooking cavity, and enhances the cooking effect of the cooking appliance by having the temperature control device control the temperature based on the detection results of the second temperature sensor.

[0117] In one embodiment according to this application, such as Figure 3 As shown in the figure, a second schematic flowchart of the control method for a cooking appliance according to an embodiment of the present invention is illustrated. The step of controlling the operation of the temperature control device of the cooking appliance based on the detection result of the temperature detection device includes the following steps S202 and S204:

[0118] S202: Obtain the fourth temperature value based on the detection results of the temperature detection device;

[0119] S204: The operating time of the temperature control device is controlled according to the difference between the fourth temperature value and the target temperature.

[0120] In this embodiment, the step of controlling the operation of the temperature control device of the cooking appliance based on the detection result of the temperature detection device is specifically defined. When controlling the operation of the temperature control device based on the detection result of the temperature detection device, a fourth temperature is first obtained based on the detection result of the temperature detection device, and then the temperature control device is controlled to run for a preset time based on the difference between the fourth temperature and the target temperature, so as to fully heat the inside of the cooking cavity and raise the temperature inside the cooking cavity.

[0121] like Figure 4The utility model discloses a fourth aspect further proposes a kind of control device 300 of cooking utensil, comprising: receiving module 310, receiving module 310 is used to receive the insertion signal of temperature probe, confirm temperature probe and probe socket of cooking utensil are connected;Acquisition module 320 is used to obtain first temperature value according to the detection result of the second temperature sensor of temperature probe;Control module 330 is used to control the temperature control device of cooking utensil to operate according to the difference of first temperature value and target temperature;Or control module 330 is also used to control the temperature control device of cooking utensil to operate according to the detection result of the temperature detection device of cooking utensil;Acquisition module 320 is also used to obtain second temperature value according to the detection result of the temperature detection device of cooking utensil;The control device 300 of cooking utensil further includes comparison module 340, comparison module 340 is used to compare second temperature value with target temperature, if the difference of target temperature and second temperature value is greater than preset threshold, then acquisition module 320 is also used to obtain third temperature value according to the detection result of second temperature sensor, control module 330 is also used to control the temperature control device of cooking utensil to operate according to the difference of third temperature value and target temperature;If the difference of target temperature and second temperature is less than or equal to preset threshold, then control module 330 is also used to control the temperature control device of cooking utensil to operate according to the detection result of temperature detection device.

[0122] The application provides a control device 300 of a cooking utensil. The control device is used in the cooking utensil. The cooking utensil comprises a box body, the box body has a cooking cavity, and the cooking utensil further comprises a probe socket and a temperature probe. The temperature probe can be detachably connected to the probe socket. When the temperature probe is connected to the probe socket, the temperature probe can detect the temperature in the cooking cavity. The control device comprises a receiving module 310. When the cooking utensil is running, the receiving module 310 is used to receive an insertion signal of the temperature probe, so as to confirm that the temperature probe is connected to the probe socket. The temperature probe is provided with a second temperature sensor. When the temperature probe is inserted into food, the second temperature sensor is located outside the food. Therefore, the ambient temperature around the food can be detected by the second temperature sensor. Meanwhile, the second temperature sensor can generate a second temperature signal. The control device 300 of the cooking utensil further comprises an acquisition module 320. After confirming that the temperature probe is connected to the probe socket, the acquisition module 320 is used to obtain a first temperature value according to the detection result of the second temperature sensor of the temperature probe. Specifically, the acquisition module 320 receives the second temperature signal generated by the second temperature sensor, and obtains the first temperature value. The first temperature value is the ambient temperature value around the food. Since the second temperature sensor is relatively close to the center of the cooking cavity, the first temperature value can accurately reflect the temperature at the center of the cooking cavity. Then the control can be performed through two different embodiments.

[0123] In a possible embodiment, the control device 300 of the cooking appliance further comprises a control module 330 configured to control the temperature control device to operate according to the difference between the first temperature value and the target temperature. That is, the temperature control device is controlled to operate according to the detection result of the temperature probe directly, instead of the detection result of other temperature detection devices.

[0124] In another possible embodiment, the cooking appliance further comprises a temperature detection device configured to detect the temperature of the cooking cavity, the temperature detection device being arranged on a wall surface of the cooking cavity and extending into the cooking cavity, so that the temperature detection device can detect the temperature in the cooking cavity. However, since the temperature detection device is far away from the center of the cooking cavity, when the volume of the food is large, the detection result of the temperature detection device is quite different from the actual temperature at the center of the cooking cavity. The control module 330 is further configured to control the temperature control device of the cooking appliance to operate according to the detection result of the temperature detection device of the cooking appliance. The acquisition module 320 is further configured to obtain a second temperature value according to the detection result of the temperature detection device of the cooking appliance. The control device 300 of the cooking appliance further comprises a comparison module 340 configured to compare the second temperature value with the target temperature. If the difference between the target temperature and the second temperature value is greater than a preset threshold, it indicates that the detection result of the temperature detection device is inaccurate. The acquisition module 320 is further configured to obtain a third temperature value according to the detection result of the second temperature sensor. The control module 330 is further configured to control the temperature control device of the cooking appliance to operate according to the difference between the third temperature value and the target temperature. If the difference between the target temperature and the second temperature is less than or equal to the preset threshold, it indicates that the detection result of the temperature detection device meets the requirement. The control module 330 is further configured to control the temperature control device of the cooking appliance to operate according to the detection result of the temperature detection device.

[0125] Since the second temperature sensor in the temperature probe is closer to the center of the cooking cavity, it can obtain a temperature value closer to the center of the cooking cavity, so that the cooking appliance can accurately obtain the temperature at the center of the cooking cavity even when the volume of the food is large. The present application improves the temperature control precision by controlling the temperature control device to operate according to the detection result of the second temperature sensor, thereby improving the temperature recovery speed in the cooking cavity and the cooking effect of the cooking appliance.

[0126] In some embodiments, optionally, the acquisition module 320 is further configured to obtain a fourth temperature value according to the detection result of the temperature detection device. The control device is further configured to control the temperature control device to operate for a preset time length according to the difference between the fourth temperature value and the target temperature.

[0127] In this embodiment, the control device 300 of the cooking appliance is further limited. When the temperature detection device detects a result, the obtaining module 320 is further configured to obtain a fourth temperature according to the detection result of the temperature detection device, and then the control device controls the temperature control device to operate for a preset time length according to the difference between the fourth temperature and the target temperature, so as to sufficiently heat the cooking cavity and increase the temperature in the cooking cavity.

[0128] The fifth aspect of the utility model further provides a cooking appliance, which comprises the control device 300 of the cooking appliance provided by the fourth aspect of the utility model.

[0129] The cooking appliance provided by the fifth aspect of the utility model has all the beneficial effects of the control device 300 of the cooking appliance because it comprises the control device 300 of the cooking appliance provided by the fourth aspect of the utility model.

[0130] The sixth aspect of the utility model further provides a readable storage medium, and the readable storage medium stores programs or instructions, and the programs or instructions are executed by a processor to realize the steps of the control method of the cooking appliance provided by the third aspect of the utility model.

[0131] The readable storage medium provided by the sixth aspect of the utility model has all the beneficial effects of the control method of the cooking appliance because the programs or instructions stored on the readable storage medium can be executed by a processor to realize the steps of the control method of the cooking appliance provided by the third aspect of the utility model.

[0132] In a possible embodiment, as shown in Figure 5 and Figure 7 The first module is a first temperature sensing unit (i.e., the first temperature sensor 112) of a probe (i.e., the temperature probe 100), which is used to sense the internal temperature of food (here, the temperature sensing unit is not limited to one or more) and is located at the probe needle head part. The second module is a probe needle head body (i.e., the probe main body 111), which is mostly made of stainless steel and is internally filled with a heat-conducting material (i.e., a heat-conducting member) such as resin to accelerate heat conduction. The third module is a signal line (i.e., the first signal line) for transmitting signals. The fourth module is an insulating and heat-insulating silica gel handle (i.e., the first handle). The sixth module is a heat-conducting metal block (i.e., the second probe part 130), which is used to conduct heat from the environment to the second temperature sensing unit (i.e., the second temperature sensor 120) of the fifth module. The seventh module is a signal line (i.e., the second signal line 131). The eighth module is a wire silica gel coating (i.e., a protective layer). The ninth module is an insulating and heat-insulating silica gel handle (i.e., the second handle 170). The tenth module is a DC plug (i.e., the plug 150).

[0133] As shown in Figure 1As shown, the probe includes a first sub-signal line 117, a second sub-signal line 118, a third sub-signal line 132, and a fourth sub-signal line 133, for conducting the first temperature sensing unit and the second temperature sensing unit. The plug 150 has a first conducting segment, a second conducting segment 151, a third conducting segment, and a fourth conducting segment 152, which are respectively communicated with the first sub-signal line 117, the second sub-signal line 118, the third sub-signal line 132, and the fourth sub-signal line 133. The first conducting segment and the third conducting segment are short-circuited to the ground signal of the driving circuit, and the second conducting segment 151 and the fourth conducting segment 152 are connected to the voltage dividing unit of the driving circuit.

[0134] In yet another possible embodiment, as shown in Figure 2 , another probe structure is provided. The difference between this probe structure and the embodiment shown in Figure 1 is that the second temperature sensing unit is replaced to the root of the probe, and the root of the probe needle body (i.e., the probe body 111) has a scale line (i.e., the limit line 115) for prompting the user not to exceed the insertion depth. The detection of the ambient temperature of the food material is realized by the second temperature sensing unit.

[0135] In yet another possible embodiment, as shown in Figure 2 , a structure schematic diagram of an oven (i.e., a cooking appliance 200) is provided. The probe base (i.e., a probe socket 230) is used for inserting a wire probe (i.e., a temperature probe 100). Inside the probe base, there is a connection line connected to the oven control unit (i.e., a temperature control device), and the cavity temperature sensing unit (i.e., a temperature detection device 220) is installed on the inner wall of the cooking cavity 211.

[0136] In yet another possible embodiment, in order to solve the problem that the oven is slow to recover the temperature when a large piece of food is put in, resulting in poor cooking effect. According to the probe scheme described herein, the sensing unit (i.e., the first temperature sensor 112) is used to sense and control the internal temperature of the food in a conventional manner. The sensing unit and the internal temperature sensor of the cavity (i.e., the temperature detection device 220) jointly control the temperature of the oven (i.e., the cooking appliance) to ensure that the cavity core temperature quickly recovers after a large piece of food is put in, and the cooking effect is ensured. As shown in Figure 1 Figure 3 Figure 6 , the control logic of the probe is shown. In the figure, a flowchart of the third control method of the cooking appliance is shown. The control method of the cooking appliance includes the following steps S302 to S306:

[0137] S302: Collecting the oven temperature by the cavity temperature sensing unit and the second temperature sensing unit;

[0138] S304: Controlling the cavity temperature according to the detection result of the cavity temperature sensing unit;

[0139] S306: comparing the difference between the target temperature and the cavity temperature with a preset threshold value, if the difference is greater than the preset threshold value, executing step S308, if the difference is less than or equal to the preset threshold value, executing step S304;

[0140] S308: controlling the cavity temperature according to the detection result of the second temperature sensing unit.

[0141] When the user inserts the probe, the oven recognizes that the probe is inserted, and the user starts the cooking function. The internal temperature sensing unit (i.e., the second temperature sensor) and the internal temperature sensor of the cavity (i.e., the temperature detection device 220) of the oven jointly control the oven, and when it is judged that there is a large difference between the set temperature and the internal temperature of the cavity (i.e., the cooking cavity), the control is switched to using the detection result of the internal temperature sensing unit (i.e., the second temperature sensor). Or when it is recognized that the user inserts the probe, the control is directly switched to using the detection result of the internal temperature sensing unit (i.e., the second temperature sensor).
